### 5.3.5.3 All-subnets-directed Broadcasts

The first version of this memo described an algorithm for distributing a directed broadcast to all the subnets of a classical network number. This algorithm was stated to be "broken," and certain failure cases were specified.

In a CIDR routing domain, wherein classical IP network numbers are meaningless, the concept of an all-subnets-directed-broadcast is also meaningless. To the knowledge of the working group, the facility was never implemented or deployed, and is now relegated to the dustbin of history.
